WALDRON (AP) — Waldron High School was placed on a temporary lockdown after officials received a threatening letter allegedly sent by a student that involved a gun.

Superintendent of Waldron Schools Suzanne Bailey told KHOG-TV she was notified about the letter Monday night, and law enforcement officers were on hand when students arrived Tuesday morning. Authorities say no children were in danger and the lockdown was lifted.

Police say the student believed to have made the threat is in custody and is being interviewed.

Officers say they don't think the student meant to carry out any violent act.
